Hello , I install 2 solar pannels 460W in serie , connect to MPPT 150/35 and BMV 712 Smart with Battery Balancer , all with 2 Battery 12V 200Ah Lithium LifePO4 with BMS connect in Serie also . I try to have the best setup is possible to protect my two battery (they not cheap), and in web and youtube is so many information with differend setup . Can you tell me if those setup is correct or need change

For the MPPT Battery Voltage 24V - Max charge current 35A - Absorption voltage 28.2V - Float Voltage 27.00V - Absorption time 2h0m - Tail current 4.0A - and no equalization

For the BMV-712 Battery capacity 200Ah - Charged voltage 27.6V - Discharge Floor 20% - Tail Current 4.0% - Current threshold 0.10A - Charge efficiency factor 99%

If you can tell me if is good or not , I will very appreciate your help , i am desperate for the right information for my setup . I am 69 years old and try to do that my self , not easy to setup correctly Thank you for your assistance Philippe

Could be correct, not completely wrong, but check the battery manufacturers specs for the voltages

Charged voltage should be 0.2V lower than absorption, so 28.0V  
Peukert would be 1.05

Rest sounds good
